Finally decided to break my brain and try making
a script for something I really need. Just a rough
draft since I don’t know what i’m doing…
Today - Flatten selected vertices to a plane (Z-Axis only).
Tomorrow - GUI and multi-Axis

Find an interesting vertex array? Flatten it!
Tuesday 2:45 AM CST
September 14, 2010
I’ve often noticed that various modifications and whatnot
in the process of modeling objects produce interesting vertex
and face patterns that I would like to use as planar surfaces
for textures (i.e. stained-glass windows, etc.).
Well, flatten them and go forth! Currently only works with
setting the Z-coordinates of selected vertices to 0. Once I
learn how to script a panel, there’ll be numerous options.
Help would be appreciated, but not compensated. 
IMPORTANT: This uses the mesh’s LOCAL coordinates, so make
sure you have it pointing the right way!
